NO! Never do this! When declaring UBOs/SSBOs, pretend that all 3-element vector types don’t exist. This includes column-major matrices with 3 rows or row-major matrices with 3 columns. Pretend that the only types are scalars, 2, and 4 element vectors (and matrices). You will save yourself a very great deal of grief if you do … Read more
In the most general sense, no. OpenGL and Direct3D only allow one index per vertex; the index fetches from each stream of vertex data. Therefore, every unique combination of components must have its own separate index. So if you have a cube, where each face has its own normal, you will need to replicate the … Read more
So the question really is Understanding 4×4 homogenous transform matrices well without the math behind the only thing that left is geometric representation/meaning which is far better for human abstraction/understanding. So what the 4×4 matrix is? It is representation of some Cartesian coordinate system and it is composed of: 3 basis vectors (one for each … Read more
OpenGL is a graphics system. It doesn’t handle “data services”, “socket services”, “http services”, or anything of the kind. It just draws stuff. Where you get the stuff for it to draw is entirely up to you.
